IMPROVEMENT IN GRAIN-BINDERS.

' Specification forming part of Letters Patent No. 39,463, dated August 11, 1863.

To all whom it may concern:

Be it known that I, W. W. BURsoN, ofAtkinson, in the county of Henry and State Illinois, have invented a new and useful Machine for Binding Grain upon the Platform of the Reaper; and I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the annexed drawin g, formin gpart of this specification, in the several figures of which similar characters of reference denote the same part.

Figure 1 is a side elevation, the wire-lever A bein gin position closed around the gavel. Fig. 2 is a plan view of the parts in the same position as in Fig. 1. Fig. 3 is a side elevation, the uprightB and brace 0 being removed; the full lines show the parts in the same position as in Fig. 1, the dotted lines the position of the parts ready to receive the gavel. Fig. 4 shows hook a. Fig. 5 shows spring-pliers b on the end of lever A. Fig. 6 shows twistingclaws c. Fig. 7 shows slide D.

My invention has reference to the binding of grain with wire upon the reaper-platform; and consists of certain combinations of devices, hereinafter to be described.

In the drawing, Figs. 1 and 3, A is the wire lever carrying the band around the gavel, supported on thetrunnions E E, moving in grooves F F in uprights B B.

The spool Gr, Fig. 2, has wound upon it the wire to be used in binding in such manner as to be unwound from the under side, covering which is the belt H fitting between the flanges of the spool and secured to the cross-bar 2, which prevents its turning with the spool, and being slotted underneath, the wire is drawn oft,

. being thus prevented from bounding 0d the spool in the rapid motions of binding, should the wire become slack. The cam-rod I passes through eyelet 3 in slide 1), also through eyelet et in support-bar K. The ratchet-rods L and L attach lever A at E and E, and act upon ratchet-pulley M of spool G, regulating the length of wire given off and the degree of tension put upon the same by means of the springs O O.

The crank P upon shaft It, upon which is secured bevel-wheel T, meshing in pinion T, is stopped over spring U by drop-catch YV, in which position the twisting-claws are in position to receive the wire.

under the spring-pliers b, which is its. position of rest.

The wheel T has upon its upper surface the cam d. The rotation of said wheel raises book a, which, driving between the jaws of pliers 1), parts them enough to allow the end of the wire to be drawn out and anew hold taken, when the hook is forced down, the elevation 9 closing the pliers by pressing thereon.

The twisting-claws are formed by slotting the enlarged end of shaft 9 obliquely, the front end being cut to the center, therear end being raised enough from the circumference of the shaft that the wire is thrown into the opened pliers by the rotation of the shaft.

The spring-pliers are formed by oorrugaling the end of lever A, from the recess h, transversely, the end being serrated. A spring is made to match the end already prepared and is riveted to A, both pieces being beveled underneath to admit point of book a, the springjaw being provided with a cutting-edge meshing closely into recess h, by which the wire is severed. The wire is heldin the twisting-claws by the front piece of slide D, flanges of B B, and upper surface of pliers b.

In operating, we wind the wire upon spool G, and having fastened the belt H over it, we draw the end of the wire S through the .slot of said belt, through eyelet 7 of slide D,

Figs. 3 and 7, and, opening springpliers b, place the wire therein, Fig. 3, dotted lines. The gavel beingplaced upon the platform Q, the handle Z of wire-lever A is shoved forward, the trunnions E E moving in grooves F F, which brings lever A in position shown in Fig. 1. While lever A is being thus brought around the gave], the ratchet-rod L acts continually upon ratchet-pulley M, putting any desired ten-- sion upon the wire S as it is thrown around the gavel. At the same time the cam-rod I presses down slide D, forcing the wire into position seen in Figs. 1 and 3. By this same movement the spring compressors X and Y are thrown around the gavel, thereby relieving the tension upon the wire.

The above-described movement puts the band around the gavel, and while lever A is being firmly held down with one hand, the other takes hold of crank P, with the finger presses down spring U, acting by rod m upon the rear end of drop-catch W, raises it out of notch 8, when the crank is turned to the left one revolution, the drop-catch W stopping it in position of starting. The rotation of crank P turns wheel T, the cam d of which raises hook a. forcing the end of said hook between the jaws of pliers b, whereby they are opened, receiving the wire S, which the rotation of twisting-claws 0 brings to them, and also allowing the end of the wire before held to be drawn out, when cam d forces down hook at and, pressing the elevation 9 of said hook upon the spring-jaw of pliers 1), assists said spring in cutting thewire. The band of the gavel being thus severed from the spool portion of the wire, the continued rotation of twisting-claws 0 securely fastens the two ends of the wire together, being held in the oblique claws by slide D, flanges on uprights B B, and upper surface of pliers b.

The gavel being thus bound, the handle Z is drawn back, when the end of lever A is raised slightly above the platform Q. The sheaf should be removed with the foot, when the lever is fully raised. While the lever A is being raised the arrangement of ratchet-rod L is such that the motion of trunnion E in groove F shall prevent the further paying off from the spool G and take up any slack wire which may have run off. a

The wire S being raised by slide D, as shown in Fig. 3, dotted lines, is entirely out of the way of the gavel, which may be shoved to the gavel, constructed and operating substantially as described.

2. The combination of the slide D, cam-rod I, and lever A, acting substantially as described and for the purpose set forth.

3. The combination of the spring-rod X and coil-spring Y with lever A and slide D, acting as set forth.

4. The combination of the spring-pliers b,

. slide D, and twisting-claws c, substantially as described.

5. The combination of the ratchet-rods L L, ratchet-pulley M, springs O O, and lever A, acting substantially as described and for the purpose set forth.

6. The combination of the spool G, wire covering-helt H, and bar 2, substantially as set forth.

7. The combination of the crank P, spring U, rod on, drop-catch W, and wheel T, acting substantially as described.

8. The combination of the hook a, cam d, and pliers I), acting substantially as described and for the purpose set forth.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.

W. W. BURSON.
